Sometimes a pharmacist will let you know that different brands are in the same bottle. It's true for many meds. The pharmacy will get an order filled by a different company, but it's the same medication-different look, etc. If you ever have a problem go or call the pharamcy-they have the exact record of how many pills are from one company, and how many are from another company, and if they're a different color or shape, etc. I also recommend verifying it from an outside source-like calling a phamacy from a different or independent company. Hey, they're paid to provide you this type of service.
